Is there any evidence that endemic doves or pigeons once occurred on the Hawaiian Islands? I mean pigeons are known to colonise the most remote islands (e.g. St Helena, Galapagos) so why not Hawaii?
Well, I could image that pigeons and doves once occurred in Hawaii, but were hunted and eaten to extinction by the early Polynesions in that way that no fossil material remained. Or the fossil material has been lost by wind, weather, and other natural events. Today there are only introduced doves and pigeons (e.g. on Waikiki)

I'm slightly confused by the conclusions concerning Pakistani collared dove. And point (ii) is particularly unsurprising!!!All samples of Pakistani collared dove shared a single clade and found to be the same species that is S. decaocto). Sequences of the Collared dove showed a very close relationship with Streptopelia roseogrisea (African collared dove) (Fig. 1). Furthermore, the phylogenetic tree provided evidence in favor of several classical theories viz; (i) Eurasian doves are close relative to African collared dove, (ii) The Mourning collared dove (Streptopelia decipiens) is not a close relative of the North American Mourning Dove, (Zenaida macroura) rather it is comparatively a close relative to Eurasian-, African- and Pakistani-collared doves, (iii) The Slender-billed Cuckoo-Dove and Brown Cuckoo-Dove belong to same species although some authorities consider it disputed [13].
... Distinct geography of Pakistan might have induced the local doves for their independent evolution. In our study, the alignment of the COI gene sequences of Pakistani dove samples showed lesser intra-species polymorphism than that of inter-species. The finding indicates the taxonomic status of Pakistani collared dove as an independent species or at least as a sister species of Eurasian and African-collareds doves.
How on earth did this article get through the review process?
Wow, no kidding, that was horrible. Is Pakistani Collared Dove considered a taxon by anyone, anywhere? I can find no reference to it.
So can I get a quick paper by collecting some Eurasian Collared-Doves here in central Illinois, call it Illini Collared-Dove and describe how it is identical in barcodes to Eurasian Collared-Dove? :-O
